==================
What is the meaning of Sentence 1? Is there any similar sentence among Sentence 2 and Sentence 4? Or do you have other similar sentences?

All are correct, but do not mean all the same thing. #1 means that he received or was given more money. "I got the prize." "I got a black eye." "I got something he didn't." It implies ONE instance, not something that happened or happens over time. "He earned/made more..." implies over a period of time, like a lifetime, a week, a year, etc. "He has got..." means that he has more in his wallet or bank account, not that he earned it or won it, etc. And, of course, "He had more..." or "earned more" is past tense whereas the others are present tense, so the meaning is quite different.

The meaning of Sentence 1 is that "he" received or possessed three times the amount of money as "I" did.

Similarly, both Sentence 2 and Sentence 4 convey the same meaning. Sentence 2 states that "he" earned or made three times as much money as "I" did, while Sentence 4 describes a past scenario where "he" had three times the amount of money as "I" had at that time.

In terms of other similar sentences, some examples include:

5. He ended up with three times as much money as I.
6. He acquired three times as much money as I.
7. He amassed three times as much money as I.
8. He accumulated three times as much money as I.

All of these sentences express the idea that "he" possesses three times the amount of money as "I."
